ROLLER FOR ROLLER COTTON-GINS.

Specification of Letters Patent.

Application filed October 22, 1910.

Patented Sept. 12, 1911. Serial No. 588,432.

To all whom it may concern:

Be it known that I, WILLIAM H. HAnRIss, a citizen of the United States of America, and a resident of Pawtucket, county of Providence, and State of Rhode Island, have invented certain new and useful Improvements in Rollers for Roller Cotton- Grins, of which the following is a specification, reference being had to the accompanying drawings, forming a part thereof.

My invention consists first in a roller for roller cotton gins, provided with a plurality of radially extending plugs fitted to suitable recesses in the roller, the outer extremities of the plugs constituting the operating friction surface of the roller. Such a construction is not only inexpensive to manufacture but is advantageous by reason of the fact that the parts constituting the friction ele ments may thereby be readily renewed as they become worn, damaged or destroyed; moreover, individual portions may thus be readily renewed where the damage or wear is 10- cal, as will be well understood. As a fur ther feature of my invention I preferably construct these plugs of cork, because I find that cork is durable, does not tend to wear the face of the bed knife employed in connection with rollers of this character, to the extent that other materials commonly used in this connection, do, and is efficient in its action upon the cotton fibers.

In carrying out my invention I employ certain novel details of construction and ar rangements of parts, all as will be fully pointed out hereinafter, and in order that my invention may be thoroughly understood, I will now proceed to describe certain structures constituting embodiments thereof, and will then point out the novel features in claims.

In the drawings: Figure 1 is a view in transverse section through a cotton gin roller constructed in accordance with my invention. Fig. 2 is a view in part side elevation and part central longitudinal section thereof, the exterior covering having been wholly removed from the core in one part of the View. Fig. 3 is an enlarged view in development of a portion of the roller surface.

The base or body portion of the roller may be of any suitable form and in Figs. 1 and 2 I have shown the same as comprising a solid core 10 provided with trunnions 11 at each end thereof by which the roller may be mounted to rotate in suitable bearings. Suitably secured to the central core is a cylindrical shell 12 provided throughout with a number of radially disposed per forations, or openings 13. A plurality of plugs 14 are mounted ,in these individual perforations 13 as shown, the plugs being conveniently of cylindrical contour to conform with the shape of the openings, the extremities of the plugs being arranged to extend slightly beyond the surface of the shell as is clearly shown in the drawings. Fig. 3 shows a development of a portion of the roller surface complete wherein it will be seen that the plugs are disposed quite close together and except for the slight spaces between them form a substantially continuous friction surface for the roller. Rollers of this general character are usually scored or otherwise provided with indentations or grooves throughout because it is found in practice that such an arrangement is conducive to a more eflicient action of the friction surface upon the cotton fibers, and the small spaces between the several plugs hence fulfil this requirement. It will be noted that in the specific arrangement shown the plugs are arranged in parallel staggered rows, the plugs of adjacent rows overlapping each other. It will be readily understood that should any portion of the friction surface in this arrangement be injured or become worn, it can readily be renewed by the removal of the damaged or worn plugs and the substitution of new ones in the place thereof. The plugs may be retained in position by the use of an adhesive material or by any other suitable means if the same be found necessary or desirable, but so far I have found that it is sufiicient merely to fit them snugly in place. The core prevents them from being driven inward toward the center of the roller, and the walls of the openings prevent their lateral displacement. In the operation of the gin the tendency is to drive the plugs inward rather than to force them outward; hence so far I have found no tendency of the plugs to become displaced. These plugs may be of any substance having the required friction surface, but I preferably form the plugs of cork for the reasons stated in the preamble of this specification.

What I claim is:

l A ginning roller for roller cotton gins provided with a plurality of radially extending cork plugs.

2. A ginning roller for roller cotton gins comprising a. member having an exterior cylindrical surface and provided with a plurality of radial cylindrical recesses projecting inward therefrom, and cylindrical plugs fitted to the said recesses, the ends whereof project beyond the said cylindrical surface.

3. In a ginning roller for roller cotton gins, the combination with a cylindrical core, of a cylindrical shell fitted thereto and provided throughout with a plurality of radially disposed cylindrical perforations, and cylindrical plugs fitted in the said perforations, the inner ends of the plugs resting upon the surface of thecore and the outer ends thereof extending beyond the outer surface of the shell.

st. A ginning roller for roller cotton gins comprising a member having an exterior cylindrical surface and provided with a plurality of radial cylindrical recesses project ing inward therefrom and arranged in a plurality of parallel staggered rows, the recesses of adjacent rows overlapping each other, and cylindrical plugs fitted to the said recesses, the ends whereof project beyond the said cylindrical surface.

5. In a ginning roller for roller cotton gins, the combination with a cylindrical core, of a cylindrical shell fitted thereto and provided throughout with a plurality of radially disposed cylindrical perforations, the said perforations being arranged in parallel staggered rows, the perforations of adj acent rows overlapping each other, and cylindrical plugs fitted in the said perforations, the inner ends of the plugs resting upon the surface of the core and the outer ends thereof extending beyond the outer surface of the shell.

6. A ginning roller for roller cotton gins comprising a member having an exterior cylindrical surface and provided with a plurality of radial cylindrical recesses projecting inward therefrom, and cylindrical cork plugs fitted to the said recesses, the ends whereof project beyond the said cylindrical surface.

7. In a ginning roller for roller cotton gins, the combination with a cylindrical core, of a cylindrical shell fitted thereto and provided throughout with a plurality of radially disposed cylindrical perforations, and

-cylindrical cork plugs fitted in the said perforations, the inner ends of the plugs resting upon the surface of the core and the outer ends thereof extending beyond the outer surface of the shell.

8. A ginning roller for roller cotton gins comprising a member having an exterior cylindrical surface and provided with a plurality of radial cylindrical recesses projecting inward therefrom and arranged in a plurality of parallel staggered rows, the recesses of adjacent rows overlapping each other, and cylindrical cork plugs fitted to the said recesses, the ends whereof project beyond the said cylindrical surface.

9. In a ginning roller for roller cotton gins, the combination with a cylindrical core, of a cylindrical shell fitted thereto and provided throughout with a plurality of radially disposed cylindrical perforations, the said perforations being arranged in parallel staggered rows, the perforations of adjacent rows overlapping each other, and cylindrical cork plugs fitted in the said perforations, the inner ends ofthe plugs resting upon the surface of the core and the outer ends thereof extending beyond the outer surface of the shell.
